What is the line type of cad dotted line?

The point-drawing line in CAD is the line shape of CENTER or CENTER2. In CAD, you can use the LINE, XLINE, RAY, PLINE, and MLINE commands to generate straight lines or line segments, but only the LINE command is used most frequently and is the most flexible.

The dotted line in CAD is the line shape of CENTER or CENTER2.

In CAD, you can use the LINE, XLINE, RAY, PLINE, and MLINE commands to generate straight lines or line segments, but only the LINE command is used most frequently and is the most flexible.

In order to ensure the corresponding relationship of "aligned length, equal width, and equal height" between the three views of the object, you should use the XLINE and RAY commands to draw several auxiliary lines. Then use TRIM to cut off the excess. If you want to quickly generate a closed filled boundary or construct a region, you should use the PLINE command. Line segments generated with PLINE can be edited with the PEDIT command. When generating multiple parallel line segments at one time, and each line segment may use different colors and line types, you can choose the MLINE command.

Extended information:

The earliest applications of CAD were in large companies in the automobile manufacturing, aerospace and electronics industries. As computers became cheaper, their applications broadened.

CAD implementation technology has undergone many evolutions since that time. When this field first started, it was mainly used to produce drawings that were similar to hand-drawn drawings. The development of computer technology has enabled more skillful applications of computers in design activities. Nowadays, CAD is not only used for drawing and display, it has begun to enter the more "intelligent" part of the designer's professional knowledge.

Many CAD drawing applications are created from scratch using design sketches and other input. Other CAD drawings are obtained from the original electronic CAD file by copying all or part of another CAD file, modifying it, and then saving it as a new file. Drawings that exist only in physical form (blueprints, designs from missing files, etc.) can be converted into CAD files using a "paper to CAD conversion" (drawing conversion, digitization, vectorization) program.
